首先簡單介紹了圖像定位和分類系統的基本概念。然后分析了幾種圖像定位和分類系統的實現方式與性能。在此基礎上，提出了一種新型圖像和分類系統實現方案：該方案采用可重配置器件FPGA 和數字信號處理器DSP 協同工作，實現了便攜式圖像處理系統。最后給出系統測試平臺設計思路，并詳細列出新型系統的性能數據。
關鍵詞：圖像采集、圖像定位、圖像分類
Abstract: This paper briefly gives the basic conception of image localization and classification system at first. Then this paper presents some existing systems dealing with object localization and classification, analyzing the performance and implementation of each work.
Basing on these descriptions, a new system for localization and classification of images using FPGA and DSP is proposed, developing a portable system for image processing. At last, the design method of the testing platform is given with comprehensive test data listed.
Keyword: Image acquisition, Image localization, Image classifcation
